Exact same thing happened, automated voice that said exactly as MG888, and eligibility for a lower rate. I thought it was for one of my cards and It transferred me. Male with Indian (as in India) accent answered. I asked him, what card? He said, Visa MasterCard. I said, But what company? Then he hung up on me! Lol. Good advice from twc from NYC: don't answer unknown caller! I thought it was my boss, so I answered. Never again!
Called - called back - call cannot be completed as dialed. spoof number - on Android use Extreme Call Blocker works better than ANY other call blocker on the planet - excellent hangup no voice mail option !!
